Siemens 6ES7468-1DB00-0AA0 S7-400 IM Cable C-Bus

The Siemens 6ES7468-1DB00-0AA0 IM cable provides a dedicated connection for the C-bus communication system in the S7-400 platform. This cable links interface modules (IM) across multiple racks for coordinated data exchange. It transmits both the C-bus and the P-bus signals between the central controller and expansion racks. The cable ensures synchronized operation of all connected S7-400 stations.

Technical Specifications

The Siemens 6ES7468-1DB00-0AA0 IM cable measures exactly 1 meter in length, making it suitable for adjacent rack connections. It transfers data at the full bus speed of the S7-400 backplane without any signal degradation. The cable uses 16-pin connectors on both ends for secure and reliable attachment. It operates with a 5 V DC signal level and supports the full C-bus protocol. The cable’s robust construction includes shielding to prevent electromagnetic interference.
